Hello all can anyone provide an answer...
Yesterday afternoon my herald was running just lovely untill a small stop for five minutes.
After pulling away the engine became rough and lumpy, holding back almost like on choke or running on 3. I recently serviced the engine including ht leads, cap, sparks. I've rechecked the leads all are fine after checking them individually with a previous one i have.
Fuel appears good. Flow from tank fine.
Any thoughs...?
